    • Method and apparatus capable of well observing or inspecting a liquid sample (20). The apparatus, for example a scanning electrode microscope, can be maintained and serviced better than heretofore. The apparatus has a film (32) including a first surface (32a) to hold the liquid sample (20) thereon, a vacuum chamber (11) for reducing the pressure of an ambient in contact with a second surface (32b) of the film (32), primary beam irradiation means (1) connected with the vacuum chamber (11) and irradiating the sample with a primary beam (7) via the film (32), signal detection means (4) for detecting a secondary signal produced from the sample (20) in response to the beam irradiation (7), a partitioning plate (14) for partially partitioning off the space between the film (32) and the primary beam irradiation means (1) in the vacuum chamber (11), and a vacuum gauge (15) for detecting the pressure inside the vacuum chamber (11).
      Damage to the film is detected by a pressure increase inside the vacuum chamber. After detecting such a pressure increase the partitioning member is moved in the path of the irradiating beam in order to prevent sample material to spill into the irradiation means.
    • 方法和能够很好观察或检查的液体样品(20)装置。 的装置,例如扫描电极显微镜,可以维护和服务比以前更好。 该装置具有一个膜(32)包括第一表面(32A)以保持液体样品(20)在其上,在真空室(11),用于与膜的第二面(32B)减少接触的环境的压力 (32),主光束照射单元(1)与所述真空室(11)连接,并且经由膜照射主光束(7)的样品(32)中,信号检测器,用于检测从产生的次级信号的装置(4) 响应于所述光束照射(7)的样品(20),分隔板(14),用于在真空室中部分分隔从薄膜(32)和初级束照射设备(1)之间的空间(11), 和真空计(15),用于检测所述真空室(11)内的压力。 损坏膜是通过在真空室内部的压力增加来检测。 检测寻求的压力增加分隔构件设置在照射光束的路径移动,以防止样品材料溢出到照射装置之后。
